Yeah - I was overthinking the joke.
Sine I read somewhere that if you switch the lenses for a different type on these glasses - the image will be clearer.
Or you can use a different type - and whilst the image isn't as clear - the illusion is stronger since the levitation appears to have greater depth.
From what I recall - Lubor went for the ChromaDepth option which allows for a greater depth to the levitation.
[Okay - just looked up the article with relevent info.]
Here is the link. It comes down to whether you use HD or STD ChromaDepth 3D glasses:

I am a huge Lubor Fiedler fan. But - I still haven't opened my Flying Carpet trick! I keep saving it for when I am most indeed of a hit of Fiedler genius. I will probably explore the trick when the 2013 Fiedler trick is released.
